If you already own or looking to own a sand filtration system for your pool, you’ll need to know how to service and clean the filter system to maintain clean, healthy water. Sand filters are relatively straight forward and easy to understand. Water passes through the filter, containing a large sum of sand. The space between sand particles allows water to pass through the filter while catching debris, removing contaminants and cleaning your pool water. Over time, debris builds in the filter and needs to be removed. About every five years, the sand in your filter will need to be removed and replaced.

Before you start, make sure you have all the necessary parts and tools. To replace the sand in your filter you will need the following:

  • Pool Filter Sand
  • Shop Vac or bucket and small shovel
  • Backwash Hose
  • Duct Tape
  • Screw Driver
  • Hose
  • Hose Clamp
  • Multiport Valve O-ring
  • Silicon Lubricant
Step 1:
Turn off your pool pump and unscrew the unions on the pvc piping leading to and from the sand filter. If you don’t have unions, you will need to cut the pipping with a small hacksaw. We recommend installing unions at this time for future maintenance.
Step 2:
Unscrew the drain cap at the bottom of the filter to release the pressure and drain any water from the sand filter.
Step 3:
Remove the multiport flange below the multiport valve, using a screwdriver. Once removed, take the multipart valve off by gently twisting and lifting from the filter tank.
Step 4:
Locate the filter pipe inside the tank and apply duct tape to the top of the filter pipe to avoid sand entering the pipe. Remove the sand inside the filter using a shop vac or by scooping it out with a small shovel.
Step 5:
After the sand is removed, take out the filter pipe and replace any broken laterals. Rinse the laterals and inside of the filter tank with a garden hose.
Step 6:
Replace the drain cap and fill the tank half way with water. Replace laterals and begin filling filter with sand to manufacturers specs.
Step 7:
Replace the o-ring on the bottom of the multipart valve and apply the silicon lubricant. Remove the duct tape, re-assemble multiport valve, secure multipart flange with a screwdriver and re-attach pvc pipes by screwing in unions tightly.
Step 8:
Apply backwash hose and turn multipart valve to the backwash position. Turn on the pump and backwash the filter for about 2 minutes.
Step 9:
Turn the pump off and turn the multiport valve to the rinse position. Turn the pump back on and let it run until the water in the pump sight glass becomes clear. Turn the pump off and switch the multipart valve back to filter and your done.
